<![CDATA[F.lux disabled in games]]>Hello,

I checked the first topic that mentions use of F.lux for fullscreen apps and when I'm in a game, F.lux is disabled despite of enable "wider slider range". Can it be fixed or is there no options ?

Thanks in advance,

Lorna and Michael (the wonderful people who are behind f.lux) have taught me during my time on this forum that the brightness level is almost as important as how much blue light is in the light source - at least as it pertains to how 'alerting' it is for the body. Of course, it's also easier on the eyes when you've been awake all day and are getting tired. We get very sensitive to light after being awake for ~14 hours.

You might also be able to reduce the amount of blue light your monitor emits by adjusting its colors using its built-in menu system.

Again, the only thing it does is it gives you more color temperatures to choose from. That's it. It doesn't do anything else. Anything you think it's doing beyond this is just The Placebo Effect. The reason it's called "wider slider ranges" is, instead of being limited to 1900K to 6500K, you can go from 1200K all the way to 9300K using the slider. That's all this setting does.

Regarding getting worse performance with windowed mode or borderless windowed mode (same thing really), do you have a FreeSync or G-SYNC monitor?

Hope it works in time.

No, it's an issue with older DirectX. The only way around this is by using Windowed Mode, or borderless windowed mode.

F.lux doesn't use system resources while the color is applied. It only uses resources when it's changing the color. Once the color is set, f.lux goes back to 100% idle.

I don't really understand. I've heard that when games are in fullscreen, they disable f.lux to use the maximum power of the GPU, is it right ?

All it does is, it gives you a wider color range to choose from, hence the name "Wider slider range".

If you want f.lux to stay enabled when you play games, then turn off the setting in the 'Disable' menu called "for fullscreen apps".
